mtlb_isletter

Matlab isletter emulation function

Description

There is no Scilab equivalent function for Matlab isletter and equivalent instructions are quite ugly, so
mfile2sci uses mtlb_isletter(A) to replace isletter(A). If you want to have a
more efficient code it is possible to replace mtlb_isletter calls:

If A is not a character string
tf = mtlb_isletter(A) may be replaced by tf = zeros(A)

If A is a character string
tf = mtlb_isletter(A) may be replaced by
tf = (asciimat(A)>=65&asciimat(A)<=90)|(asciimat(A)>=97&asciimat(A)<=122)
